SummaryThe relationship between haematocrit and cardiovascular risk factors, particularly blood pressure and blood lipids, has been examined in detail in a large prospective study of 7735 middle-aged men drawn from general practices in 24 British towns. The analyses are restricted to the 5494 men free of any evidence of ischaemic heart disease at screening.Smoking, body mass index, physical activity, alcohol intake and lung function (FEV1) were factors strongly associated with haematocrit levels independent of each other. Age showed a significant but small independent association with haematocrit. Non-manual workers had slightly higher haematocrit levels than manual workers; this difference increased considerably and became significant after adjustment for the other risk factors. Diabetics showed significantly lower levels of haematocrit than non-diabetics. In the univariate analysis, haematocrit was significantly associated with total serum protein (r = 0*18), cholesterol (r = 0.16), triglyceride (r = 0.15), diastolic blood pressure (r = 0.17) and heart rate (r = 0.14); all at p <0.0001. A weaker but significant association was seen with systolic blood pressure (r = 0.09, p <0.001). These relationships remained significant even after adjustment for age, smoking, body mass index, physical activity, alcohol intake, lung function, presence of diabetes, social class and for each of the other biological variables; the relationship with systolic blood pressure was considerably weakened. No association was seen with blood glucose and HDL-cholesterol. This study has shown significant associations between several lifestyle characteristics and the haematocrit and supports the findings of a significant relationship between the haematocrit and blood lipids and blood pressure. It emphasises the role of the haematocrit in assessing the risk of ischaemic heart disease and stroke in individuals, and the need to take haematocrit levels into account in determining the importance of other cardiovascular risk factors.

Background Cardiovascular diseases remain the leading cause of death worldwide. Atherosclerotic process increases rapidly during adolescence. Physical activity is considered important in this period to modify cardiovascular risk factors, thus preventing disease in the future.Objective To determine whether different physical activity status in adolescence can influence body mass index (BMBMI), waist-to-hip ratio, blood pressure (BP), and blood lipid profile.Methods This was a cross-sectional descriptive study, conducted from December 2009 to January 2010. Adolescents who fulfilled the study criteria were classified into high and low physical activity category. Further examination including body mass index, waist-to-hip ratio, blood pressure, and blood lipid profile were performed.Results Adolescents with high physical activity had higher, but statistically insignificant, BMBMI compared to adolescents in the P=0.493] and significantly lower waist-to-hip ratio [0.80 (range 0.73-0.9) vs.. 0.82 (range 0.7-0.9), P=0.019]. Difference in BP was not statistically significant between both groups [diastolic BP (70 (range 60-90) mmHg vs. 70 (range 60-90) mmHg, P=0.148; systolic BP 100 (range 90-130) mmHg vs. 100 (range 90-140) mmHg, P=0.228)]. Blood lipid examination in the high activity group showed significantly higher HDL cholesterol and lower triglyceride compared to the low activity group [HDL 59.8 (SD 11.8) mg/dL vs. 54.7 (SD 8.9) mg/dL; p=0.044; triglyceride: 60 (range 32-203) mmHg vs. 82 (range 37-198) mmHg, P=0.014]. Total and LDL cholesterol [total cholesterol 169.8 (SD 28.6) mmHg vs. 181.2 (SD 30.8) mmHg, P=0.107; LDL 103.6 (SD 26.8) mmHg vs. 114.1 (SD 27.3) mmHg, P=0.100] were lower in the high activity group but not statistically different in both groups.Conclusions Adolescents with high physical activity show less cardiovascular risk factors compared to those in the low physical activity group.

Noncommunicable Diseases (NCDs) merupakan salah satu penyebab kematian utama di dunia. Kurangnya aktivitas fisik dapat meningkatkan risiko penyakit ini. Meskipun telah banyak penelitian yang menyelidiki tentang hubungan aktivitas fisik dan faktor risiko penyakit kardiovaskuler, hanya terdapat beberapa penelitian di Indonesia yang menelaah tentang peran aktivitas fisik dalam perkembangan penyakit kardiovaskuler. Penelitian ini bertujuan untuk mendeskripsikan tentang tingkat aktivitas fisik dan menyelidiki hubungannya dengan faktor risiko penyakit kardiovaskuler pada karyawan kantor di lingkungan Universitas Sebelas Maret (UNS). Penelitian ini menggunakan desain penelitian potong lintang, dengan jumlah sampel sebanyak 44 orang. Data level aktivitas fisik diperoleh dari International Physical Activity Questionnaire (IPAQ). Sedangkan faktor-faktor risiko penyakit kardiovaskuler (gula darah, kolesterol, tekanan darah, lingkar pinggang, dan IMT) diukur dengan menggunakan alat ukur yang sesuai. Hasil penelitian menunjukkan bahwa level aktivitas fisik karyawan berkategori Rendah sebesar 6.82%, Sedang sebesar 72.73%, dan Tinggi sebesar 20.45%. Berdasarkan uji Pearson Correlation, tekanan darah baik sistolik dan diastolik mempunyai hubungan yang signifikan dengan level aktivitas fisik. Tidak ada hubungan yang signifikan antara level aktivitas fisik dengan faktor risiko lainnya dalam penelitian ini. Secara umum penelitian ini menunjukkan bahwa level aktivitas fisik karyawan di lingkungan UNS adalah berkategori sedang, dan tekanan darah mempunyai hubungan yang signifikan dengan aktivitas fisik. Physical activity level and cardiovascular risk factors among university employees AbstractNoncommunicable Diseases (NCDs) are one of the leading deaths in the world. Insufficiency of physical activity (PA) escalate the risk of NCDs. Although the reports of the studies investigating the relationship between PA and cardiovascular risk factors are abundance, only a few studies in Indonesia examined the role of PA in the development of cardiovascular diseases. The aim of this study was to describe the level of PA and investigate the relationships between PA and cardiovascular risk factors among UNS employees. This was a cross sectional study with a sample of 44 university employees. PA level was assessed using IPAQ. Meanwhile cardiovascular risk factors such as plasma glucose, cholesterol, blood pressure, waist circumference, and BMI were measured using an appropriate tool for each measure. The results revealed that participants with low level of PA (6.82%), moderate category (72.73%), and high category (20.45%). Pearson Correlation analysis showed blood pressure both systolic and diastolic had a significant association with PA level. There was no a significant association between PA level and others cardiovascular risk factors in this research. Generally, this study exhibited the level of PA among UNS employees in the moderate category, and blood pressure had a significant association with PA.

Physical activity (PA) and exercise training (ET) are highly effective in the prevention of cardiovascular disease (CVD) via improvement of cardiovascular risk factors (CV RFs), such as blood pressure (BP), lipid profile, glycaemic control, body fat mass, and inflammation. In the first part of this chapter, we describe the currently observed effects of PA and exercise intervention on these RFs. In the second part, we explain which exercise modalities should be selected to optimize these CVD RFs, especially for those patients with multiple CVD RFs.

Physical activity is an important component of cardiovascular health. The fact that physical activity is also associated with a substantial number of cognitive and academic benefits, therefore schools teachers can be an important role model in promoting a physically-active lifestyle in school children. The aim of this study is to examine the levels of physical activity (PA) and its association with cardiovascular risk factors in a sample of school teachers. Forty-nine (n=49) teachers from primary and secondary schools around Klang Valley urban areas were recruited. The PA level was determined using pedometer, worn for three consecutive days. Anthropometric measurements and blood samples were collected to determine cardiovascular risk factors. Findings showed that the school teachers recorded an overall mean (± SEM) of 7707 ± 490 steps/day, which is below the recommended target of 10 000 steps per day. According to pedometer-determined physical activity indices proposed by Tudor-Locke and Bassett (2004), 20.83% of the sample were classified as ‘sedentary’ (<5000 steps/day), 35.40% were ‘low active’ (5000 – 7499 steps/day) and only 18.70% achieved more than 10 000 steps/day. According to Asian BMI cut-off points, 43% of the teachers were categorized as overweight and obese (>23 kg/m2). The mean values for waist circumference, fasting blood sugar, and cholesterol level, systolic and diastolic blood pressure were 83.96 ± 1.90 cm, 5.41 ± 0.26 mmol/l, 4.64±0.26 mmol/l, 118.90 ± 1.72 mmHg and 72.40±1.58 mmHg respectively. Fisher Exact Test shown that there were significant association between daily step and age category. Daily steps weakly negative correlated with systolic blood pressure (r = -0.024, p > 0.05) as well as blood sugar levels (r = -0.061, p> 0.05), diastolic blood pressure (r = -0.079, p> 0.05), body mass index (r = -0.271, p> 0.05), waist circumference (r = -0.196, p> 0.05), as well as blood cholesterol levels (r = -0.037, p> 0.05). In conclusion, there were weak negative correlations between steps per day and cardiovascular risk factors. Generally, the level of physical activity in the sample of teachers needs to be improved. Interventions aimed at promoting PA among school teachers may be warranted in the future.

Abstract BackgroundThe impact of occupational physical activity (OPA) intensity, considering adults work many hours a day, on health is unknown. The present study aims to evaluate the association between the high intensity of OPA and cardiovascular risk factors of employees.MethodsA cross-sectional study was carried out in the “Fomento de Construcciones y Contratas S.A. Company” (FCC S.A. Delegation) in 2017, Spain. The intensity of OPA of each employee was classified by work categories in low (≤ 3 METs) or high (> 3 METs). Health and lifestyle data of employees were collected on medical consultation in the workplace.ResultsAssociations were analyzed between the high intensity of OPA and cardiovascular risk factors of employees. 751 employees, 55.5% (n = 417) with high intensity of OPA. An 82.2% (n = 245) of employees with low intensity of OPA presented overweight/obesity compared with 69.0% (n = 171) with high intensity of OPA employees (p < 0.001). In men, high intensity of OPA is negatively associated with Body Mass Index (BMI) (B: -0.042, p = 0.003), waist circumference (B: -0.027, p < 0.001) waist-hip ratio (B: -5.484, p < 0.001), cholesterol (B: -0.007, p = 0.001) and triglycerides (B= -0.003, p = 0.025). In women, high intensity of OPA was positively associated with blood pressure (BP) (systolic BP: B = 0.036, p = 0.005 and diastolic BP: B = 0.040, p = 0.021).ConclusionsIn conclusion, the high intensity of OPA is associated with less cardiovascular risk factors in men, whereas women are associated with high levels of blood pressure, suggesting an influence of gender and work categories.

Abstract The association of moderate to vigorous physical activity and sedentary behavior performed in the school context with cardiovascular risk factors is unclear. Thus, the purpose of this study was to evaluate whether MVPA and SB during school time are associated with single and clustered cardiovascular risk factors in 10- to 16-year-old school students. This study used the baseline data from a non-randomized controlled clinical trial (“MEXA-SE”) conducted on 6th to 9th-grade students from schools in Florianopolis, Brazil. Skinfolds, resting blood pressure, 20-m shuttle-run test, fasting glucose, triglycerides, total cholesterol, high-density lipoprotein cholesterol, and white blood cell counts were obtained. MVPA and SB were objectively measured with accelerometers. A minimum of 180 minutes was considered valid school-time for analysis. Multiple linear regression adjusted for age, sex and habitual physical activity was used. School-time MVPA was positively associated with the peak VO2 (β = 0.17 ml.kg.min-1), and inversely associated with sum of four skinfolds (β = -0.96 mm), diastolic blood pressure (β = -0.36 mmHg), systolic blood pressure (β = -0.301 mmHg); triglycerides (β = -1.49 mg.dL-1), and clustered cardiovascular risk factors (β = -0.123). School-time SB was positively associated with clustered cardiovascular risk factors (β = 0.033). In conclusion, independently of habitual physical activity level, school-time MVPA and a lower time in SB were associated to single and clustered cardiovascular risk factors. Thus, the promotion of strategies aimed increase MVPA and reduce SB at school may prevent the onset and early accumulation of cardiovascular risk factors in adolescence.

Background: High-density lipoprotein cholesterol (HDL-C) as an invaluable predictor is used to determine the risk of heart diseases and evaluate the effectiveness of lipid-lowering therapies. Objectives: In this study, we aimed to investigate the association between HDL cholesterol level and some cardiovascular risk factors in the patients referring to the Heart Clinic of Birjand, Iran, during 2016 - 2017. Methods: In this cross-sectional study, 410 patients referring to the Heart Clinic of Birjand, Iran, during 2016 - 2017 were selected. Then using a questionnaire, complete demographic and biochemical data were collected and statistically analyzed for assessing the effects of some lifestyle factors such as the diet and physical activity on the serum level of HDL. Finally, all the results were analyzed by SPSS software (version 15). Results: In our study, the majority of dyslipidemic people had low levels of HDL (58.8%). Most of the participants were in a poor health condition according to BMI and physical activity, in a moderate health status in terms of smoking and cholesterol and fasting blood glucose (FBS) levels, and finally in the ideal health group in terms of the diet and blood pressure. The HDL level was significantly associated with physical activity, FBS, BMI, and blood pressure (P < 0.05). Conclusions: Considering the association between persistent cardiovascular risk factors and HDL cholesterol level, encouraging people to adopt a healthy lifestyle can help prevent cardiac diseases.

Introduction Physical activity (PA) plays an important role in the prevention of cardiovascular diseases, especially in children. Previous studies which investigated the role of PA and sedentary time (ST) in cardiovascular disease used different measurements and found inconsistent results. The current study used recommended standardized measures and provides an overview of PA and ST among Dutch primary school children and their associations with cardiovascular risk factors. Methods 503 children (55% girls, mean age (± SD) 10 ± 1y) were included. PA (total PA, lightPA and moderate to vigorous PA (MVPA)) and ST were measured with the Actigraph GT3X accelerometer. PA in different domains was measured with the BAECKE questionnaire. Cardiovascular risk factors included BMI z-score, waist circumference, blood pressure (z-score) and estimated cardiorespiratory fitness (CRF) as measured with the 20 meter shuttle run test. Results Children spent 57 ± 20 min/day (8%) on MVPA and 42% of the children reached the MVPA guideline of 60 min/day. Total PA and MVPA (h/day) were negatively associated with BMI z-score (B = -0.452, p = 0.011) and waist circumference (B = -3.553, p = 0.011) and positively associated with CRF (B = 2.527, p = <0.001). ST was positively associated with BMI z-score (B = 0.108, p = 0.048) and waist circumference (B = 0.920, p = 0.033). No significant associations were found between total PA or PA intensities and blood pressure. Conclusion This study used standardized measures of PA and therefore created an accurate overview of PA, ST and their associations with cardiovascular risk factors. PA and ST were associated with BMI z-score, waist circumference and CRF. The findings emphasize the importance of promoting MVPA in children, but also highlight the potential benefits of reducing ST to improve cardiovascular risk factors.
